One or more devices are provided that are configured to detachably engage within a modular system. The one or more devices are expandable to provide a surface to perform work.

Work structure for use with modular storage system

A ladder is provided. The ladder includes coupling components that couple modular storage elements to the ladder. The ladder includes various components to facilitate moving, carrying, and placing the ladder.

Increased and improved functionality for a ladder

A storage case includes a base including a lower surface, walls extending from the lower surface, and a plurality of recesses arranged in a grid adjacent the lower surface. The lower surface and the walls define a cavity, and each recess has a double bayonet shape defining a partially circular shape with a pair of bayonet channels. The storage case further includes a peg positioned within the cavity and having an elongated body configured to support a tool accessory. The elongated body has a first end and a second end opposite the first end, and the first end includes a bayonet projection. The bayonet projection is alternately receivable in each of plurality of recesses by a bayonet style coupling, and the peg is orthogonal to the lower surface of the base when coupled to each of the plurality of recesses.

Modular tool container

A tool, such as a respirator or gas mask, is provided. The respirator includes a body, a filter, an upper and lower strap, and a locking mechanism. The locking mechanism enables quick-release for fitting and/or adjusting the respirator on a user's head or face. In various embodiments, inelastic and elastic properties of the straps and/or a cord in the entwined region of the locking mechanism enhance the quick-release fit and adjustment of the locking mechanism.

Respirator

The systems described in this disclosure can be used in construction settings to facilitate the tasks being performed. The location of projectors and augmented reality headsets can be calculated and used to determine what images to display to a worker, based on a map of work to be performed, such as a construction plan. Workers can use spatially-aware tools to make different locations be plumb, level, or equidistant with other locations. Power to tools can be disabled if they are near protected objects.

Spatially-aware tool system

One or more devices for coupling lighting elements to safety headwear are described. The devices include an element that emits light, a unit that provides power, and a coupling element to couple the device to safety headwear.

Safety headwear systems and accessories

A hard hat attachment system is described with front, back, and side mounts to support various accessories. Mounts of hard hat receive slots of a bracket that fit around the ridges. Auxiliary ridges receive clips within ports. The user customizes the hard hat for the particular task with the preferred accessories used to complete the job. For example, lamps, face-shields, reflectors, tool carriers, and eyeglass holders are interchangeably releasably coupled to mounting and/or auxiliary ridges on the hard hat. In this way, the hard hat is customized and/or modified to support a wide variety of accessories that are securely and releasably attached to mounting and/or auxiliary ridges without destructive alterations to the hard hat. Brackets couple to mounts and clips couple to ports to secure and/or lock various accessories in place during operation and prevent accidental knocks or jarring the accessory loose.

Hard hat attachment system and saftey equipment

Various embodiments of a jobsite keep out zone system are provided. The system includes one or more detectors configured to determine when an intruder is within and/or is approaching a protected area. In response to the determination, one or more alarms and/or notifications are generated.

Keep out zone system

Various carrying mechanisms to transport a storage device, container or unit are shown. The carrying mechanisms actuate between various positions that may interfere with opening a lid of the storage unit. Various configurations of the carrying mechanisms reduce their profile when in use. Also described are multi-segmented carrying mechanisms that provides a beneficial weight distribution while facilitating actuating the carrying mechanism between different positions.

Storage device with handle

A laser level alignment tool is shown. The laser level alignment tool includes magnetic mounts located along a perimeter of body. A laser level is coupled to the body off center from a center point of the laser level alignment tool. The magnetic mounts may be height adjustable relative to the body.

Laser level alignment tool

A laser projection device with compact frame is provided, as is a corresponding frame or mount for one or more laser projection devices. In one embodiment the frame or mount includes a coupling interface that permits multiple coupling positions with respect to a laser projection device, such as at 90 degree intervals.

Laser projection tools and mounting accessories
